Re: LSx swap Headers for 67-87s
Okay, I received mine a few days ago but, before I unpackage them, I need to know if they'll work with my 6L80E trans, I'm running the CPP mounts if that matters.

Re: LSx swap Headers for 67-87s
The '63-'87 frames are basically the same in the engine compartment area. The one difference is that the '68-'87 frame top flange is a little narrower than the '63-'67 frames, to allow for the big block exhaust manifolds. Without seeing a set of these headers installed, it's hard to say if you will have to trim the top flange of your frame or not.

66ChevyMax used the Doug Thorley Headers #323Y-C on his "Mesquite 1966 C10 - LS3 W/Air Ride" He posted the pictures and said that they fit great. http://67-72chevytrucks.com/vboard/s...=492168&page=9 post number 221. It looks like these are the only one's that fit with out any crazy frame mods. Do you have these in stock and if so can you give me a price on them? Thanks, Robert |
